A/c clutch bearings went out on my 2000 Dodge Durango 4.7l.

Customer Question

a/c clutch bearings went out on my 2000 Dodge Durango 4.7l. Replaced clutch. Bench tested new clutch and it engages fine with 12v applied. Will not engage when connected to electrical system.
JA: How many miles are on the clutch? Has it been slipping or sticking?
Customer: Junk yard clutch so I don't know. Fuse is good, relay has power to it, but do not have 12v at electrical connection for clutch. Is there another relay or fuse I need to look at?
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: When I connect the clutch directly to a 12v power source it engages.
JA: Anything else you think the mechanic should know?
Customer: no

Hello and welcome to JustAnswer!

There are quite a few things that will prevent the compressor from engaging but if it worked until the compressor clutch was replaced and is now not being powered then I would first suspect a charge issue. If pressure is too low then the compressor will not be allowed to engage.

Was the system charged after the compressor was reinstalled?
